Types

type LokiReader

type LokiReader interface {
	Query(start time.Time, end time.Time) ([]time.Time, error)
	QueryCountOverTime(queryRange string, now time.Time, cache bool) (float64, error)
}

type Reader

type Reader struct {
	// contains filtered or unexported fields
}

func NewReader

func NewReader(writer io.Writer,
	receivedChan chan time.Time,
	useTLS bool,
	tlsConfig *tls.Config,
	caFile, certFile, keyFile string,
	address string,
	user string,
	pass string,
	tenantID string,
	queryTimeout time.Duration,
	labelName string,
	labelVal string,
	streamName string,
	streamValue string,
	interval time.Duration,
	queryAppend string,
) (*Reader, error)

func (*Reader) Query

func (r *Reader) Query(start time.Time, end time.Time) ([]time.Time, error)

Query will ask Loki for all canary timestamps in the requested timerange. Query blocks if a previous query has failed until the appropriate backoff time has been reached.

func (*Reader) QueryCountOverTime

func (r *Reader) QueryCountOverTime(queryRange string, now time.Time, cache bool) (float64, error)

QueryCountOverTime will ask Loki for a count of logs over the provided range e.g. 5m QueryCountOverTime blocks if a previous query has failed until the appropriate backoff time has been reached.

func (*Reader) Stop

func (r *Reader) Stop()
